    Abstract: The inventors discovered that the adhesion molecule CAR, known to be localized in intracellular adhesion sites, functioned as an adhesion molecule for activated lymphocytes. Further, the inventors identified CARL, a novel CAR ligand expressed in lymphocytes, and clarified that the ligand was expressed selectively in Th1 cells. In addition, they found that anti-CAR antibodies could inhibit the adhesion of activated lymphocytes to CAR molecules. Thus, the present invention provides methods for detecting Th1 cells using CAR or anti-CARL antibodies, and methods of screening for inhibitors suppressing the adhesion of Th1 cells using the binding between CAR and CARL as an index. Furthermore, the present invention relates to methods of screening for inhibitors of the binding between CAR and CARL, antibodies that inhibit the binding between CAR and CARL, and therapeutic compositions comprising these antibodies. These are expected to be useful in diagnosing diseases, such as inflammation, in which infiltration of Th1 cells is involved, and in providing pharmaceutical agents for alleviating such diseases.

    Abstract translation: 本发明人发现已知局限在细胞内粘附位点的粘附分子CAR用作活化淋巴细胞的粘附分子。 此外，本发明人鉴定了CARL，一种在淋巴细胞中表达的新型CAR配体，并阐明了配体在Th1细胞中有选择性表达。 此外，他们发现抗CAR抗体可以抑制活化淋巴细胞对CAR分子的粘附。 因此，本发明提供了使用CAR或抗CARL抗体检测Th1细胞的方法，以及使用CAR和CARL之间的结合作为指标筛选抑制Th1细胞粘附的抑制剂的方法。 此外，本发明涉及筛选CAR和CARL之间的结合抑制剂的方法，抑制CAR和CARL之间的结合的抗体以及包含这些抗体的治疗组合物。 预期这些可用于诊断涉及Th1细胞浸润的疾病，例如炎症，以及提供减轻这些疾病的药物。
